She pushed back from the bench and walked the narrow aisle between humidity cabinets. The old lab smelled faintly of solvent and paper, warmed by the sunlight slanting through dusty blinds. Her mentor, Ravi, had always said standards are the secret hero of science — the invisible grammar that lets different laboratories speak the same language. Lina had to find the right dialect.
The team decided to take a sample of the warped sheets and perform some tests to determine the cause of the warping. They started by conditioning the sample according to the ASTM D618-21 standard and then measured its dimensions and flatness.
